APPARATUS FOR MAKING AND BURNING GASEOUS FUEL.

SPECIFICATION forming part of Letters Patent No. 371,956, dated October25, 1887.

Application filed September ll, 1886. Serial No. 213,277. (No model.)

T ctZZ whom, it may concern:

Be it known that we, JOSEPH LooKE, of Glenwood, and SoLoN O. RICHARDSON,J r., of \Vakefield, both in the county of Middle' sex and State ofMassachusetts, have invented certain new and useful Improvements inApparatus for Making and Burning Gaseous Fuel, of which the following isa specification.

lhis invention is an improvement on the ap 1o parat-us shown in ourLetters Patent of the United States, dated September 14, 1886, No.849,228, said apparatus consisting of, first, an externally-heatedoil-vaporizing .chamber or retort having means for the discharge of oilin jets against its inner surface, the oil being vaporized within theexternally-heated retort, and orifices for the escape and combustion ofthe vaporized oil, and, secondly, asteanrpipe communicating with asuitable steam-genersubstantially parallel with and in close relation tothe orifices in the vaporizing-retort,

whercat the vaporized oil is discharged and consumed. Said steam-pipe ishighly heated by the heat supplied by the apparatus, so that the steamtherein is superheated. The steampipe is provided with orifices ornozzles for the escape of the steam in jets coinciding with the jets offlame from the vaporizedoil, so 0 that the gases of the steam enter theflames of the vaporized oil and make the combustion of the latter moreperfect and produce a very high degree of heat. The union of the steamwith the flame and products of combustion of 5 the vaporized oil takesplace after the latter is ignited.

Our present invention has for its object, first, to so arrange theignition and heating devices, in connection with a single retort, that 0the latter will be uniformly heated, and the partial condensation ornon-vaporization of the hydrocarbon at one side, as in the case wherethe ignition devices are located in one side only, is preventedsecondly, to increase the capacity of the retort and its accompanyingsteam-pipe, so that more flame may be produced by the conjoint action ofa single retort and steam-pipe than in any former ap paratus; and,thirdly, to enable the heat produced by the combustion of the vaporizedoil to generate the steam that is employed to facilitate the combustion,thus making the apparatus available at points where there is nosteam-boiler.

To these ends our invention consists, first, in the combination of anexternally-heated oilvaporizing chamber or retort having two series ofburners or orifices-one at each sidemeans for discharging hydrocarbon injets against its inner surface, and a steam-supply 5 pipe arranged oversaid retort and having two series of orifices coinciding with the twoseries of orifices in the retort, the arrangement being such that thetwo series of flames from the vaporized oil intersect and mingle withthe 6 two series of jets from the steam-pipe.

The invention also consists in the combina tion, with the retort, of awater pipe or pipes extending along the same and arranged to be heatedby the flames from the burners thereof and communicating with theperforated steainpipe, steam being generated in said pipe or pipes andsupplied thereby to the perforated steam-pipe, all of which we will nowproceed to more fully describe.

Of the accompanying drawings, forming a part of this specification,Figure 1 represents a perspective view of our improved apparatus. Fig. 2represents a transverse section of the same, showing by dotted lines aheater- 8o casing surrounding the apparatus.

The same letters of reference indicate the same parts in all thefigures.

In the drawings-A represents an iron chamher or retort, preferably ofthe form in crosssection shown in Fig. 2, its base or lowerportion beingenlarged to form two outwardlyprojecting portions, a a, one at each sideof the retort. In the upper side of each portion a are formed a seriesof orifices or burners, b, where the vaporized oil from within theretort is ignited, as in our apparatus above referred to.

c 0 represent pipes connected to a suitable source of hydrocarbon-oilsupply, D, controlled by a suitable valve, d, and entering the upperportion of the retort, within which they are provided with perforations70, arranged to discharge the oil in jets against the heated inner sidesof the retort, the oil being vaporized zoo in the retort. The vaporpasses out through the burners b b and is there ignited.

. 6 represents a steam-pipe placed over the center of the retort andextending lengthwise thereof. Said pipe receives steam from any suitablegenerator, and has two series of orifices,ff, coinciding with theburners b b of the retort and arranged to directjets of steam into theflames rising from said burners, the two series of flames being suppliedwith steam from a single pipe, as shown in Fig. 2.

It will be seen that by providing the retort with two series of burnersand the steam-pipe with two series of discharge-orifices we get a largeamount offlame and heat in an apparatus of small compass. 1

Means such as are dcsci'ibed in our former patent may be used for thepurpose of heating the retort before the apparatus is in operation.

In the drawings of the present case we have represented a gas-supplypipe, B, provided with and controlled by a suitable valve, Z, and havingtwo'parallel branches, 0 0, extending horizontally beneath the chamberA, and each provided with a series of orifices, at, through which gaspasses for ignition.

Ina case, as in our former patent, where the vapor-ignition orifices areat one side only of a retort, the same becomes more heated at said sidethan at the other, and in consequence the entering hydrocarbon does notcompletely vaporize on the least-heated side, thus causing a proportionof said hydrocarbon to flow to and rest upon the bottom of the retort.In the present case such an objection is not pos sible, for the reasonthat the retort is uniformly heated throughout by the gas and vapordevices, and the hydrocarbon is thus uniformly vaporized.

When the apparatus is to be used at points where there is -nosteam-boiler, we extend a. water pipe or pipes, 6, along the side orsides of the retort above the burners b, so that they will be subjectedto the flames from the retort, said pipe being connectedsat one end, a,with a source of water-supply and at the other end with the perforatedsteam-pipe e. -A valve, 0, controls the source of water or steam supply.Steam is generated in the pipe t by the flames from the burners b, andsupplied thereby to the perforated pipe 6.

It is obvious that the last-described imb provement can be used with theapparatus described in our former patent.

\Ve claim- 1. The combination, with a single retort having orifices ateach side thereof, as described, of an external gas-pipe having orificesand adapted to externally heat said retort, a pipe extending into theretort and provided with orifices to adapt it to spray oil in jetstherein, and a'steam or water pipe having two series of orifices adaptedto discharge steam. into the flames from both series of retort-orifices,substantially as set forth.

2. The combination, with a single retort having a series of orifices ateach side thereof, of means for discharging oil in jets against theinner surface of said retort, and a Water-pipe coiled above theretort-orifices to be heated by the flames therefrom and having twoseries of discharge-orifices to discharge jets of steam into the flamesfrom the retortorifices, substantial] y as set forth.

In testimony whereof we have signed our names to this specification, inthe presence of two subscribing witnesses, this 3d day of September,1886.
